Tissue Microdissection is a laboratory technique used to isolate specific cells or regions from a larger tissue sample. This process allows researchers to study the characteristics and functions of particular cell types in detail, which is essential for understanding diseases and developing targeted therapies. The technique often involves using a microscope and specialized tools to carefully cut and extract the desired tissue sections. Laser capture microdissection is a common method that uses a focused laser beam to precisely select and remove cells, ensuring that the integrity of the surrounding tissue is maintained for further analysis.
